The first part introduces MPA's historical development in America and its particular characteristics. This partmainly focuses on 5 main characteristics, namely,(1) the development of practical skills as the highest priority in their educational formation,(2) the experience-oriented enrollment system;(3) the perfected curriculum setting,(4) the effective and flexible teaching methods, and (5) the highly trained faculty. The second part analyzes the background and key problems of Chinese MPA's education. It includes a lack of specialized educational aims, an overly grade-conscious enrolment system, a need for a more flexible curriculum, a shortage of "case-oriented" teaching methods and the dearth of a highly trained faculty. The third part proposes a theoretical framework based on the MPA educational model.

本文首先阐述了美国MPA教育的发展历程，并在追溯历史的基础上总结了美国MPA教育的主要特点，即：能力为先的培养目标、注重经历的招生办法、完善多样的课程设置、灵活有效的教学方式以及专兼结合的师资队伍五个方面；然后分析了我国MPA教育产生与发展的宏观背景与学科背景，并从MPA教育微观层面对我国目前存在的主要问题进行剖析，这些问题包括培养目标缺乏个性、招生录取偏重分数、课程设置弹性不足、案例教学较为薄弱、队伍建设有待加强；再从MPA教育的学科性质、培养目标、学科基础、课程设置、馨糕孺教学方法等方面构筑了MPA教育的基本理论框架：最后，提出了我国MPA教育改革与发展的基本思路与主要对策，思路着眼于MPA教育的长远发展，对策主要针对目前我国MPA教育存在的主要问题，包括：适时调整宏观政策、加大教学创新力度、强化师资队伍建设、加强硬件环境建设以及构建开放教育网络五个方面。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
